Key Valuation Factors

• Material and Construction: This piece is a molded simulated cameo made from plastic or resin, surrounded by a faux-pearl cream-colored border. Because it is molded rather than hand-carved from natural shell, agate, or authentic Wedgwood jasperware, it falls into the category of affordable collectible costume jewelry.
